CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 507,351, dated October2 l, 1893.

Application filed February 24, 1892- Serial No. 422,673. (No model.)

T0 at whom it may concern:

Be it known that I, THOMAS CARNEY, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Cash Registers andIndicators, of which the following is a description, reference being hadto the accompanying drawings, forming part of this specification.

Heretofore, in machines of this character which have employed a seriesof indicators or tablets representing the respective amounts to beindicated and registered, and a series of key-levers representingcorresponding amounts, the indicators have usually been thrown intoview, to make the indications, by the depression of the front ends ofthe keylevers and have been caught and held in view by some suitablesupporting device when the key levers were released and reset to normalposition. Uponthe operation of another lever the exposed indicator wouldbe released and withdrawn from view, while the indicator correspondingto the newly operated lever would be lifted into view and held up by thesupporting device.

In my improved machine the indicators are not lifted into view upon thedepression of the front ends of the key-levers, as heretofore, but uponthe re-setting of the keys and consequent lifting of their front endsand lo wering of their rear ends, the result being that when the frontend of any key-lever is depressed its corresponding indicator remainsout of sight until the lever is released, and then, as the lever returnsto normal position, the indicator is lifted into view.

In the accompanying drawings Figure 1 represents a side elevation of theframe and indicating mechanism of a cash register, illustrating onemethod in which my new mode of operation may be carried out, a portionof the near side of the framework being broken away to expose the partsbeyond it. Fig. 2 is a front elevation ofthe right and left hand sidesof the machine, (the middle portion being broken away,) showing onlythat part of the machine which is in rear of the line 22 of Fig. 1. Fig.3 is a detail view showing a modified form of connecting device betweenthe key levers and lifting levers.

The same letters of reference are used to indicate identical parts inall the figures.

The indicators A are supported upon vertical rods 13 carried in' guidesC D, the rods preferably being provided with collars E resting upon thelower guide D. To aid in resetting the indicators the rods B may besurrounded by spiral springs F confined between the collars E and upperguide 0. These springs will be compressed when the rods 13 are liftedand will assist the gravity of the rods and indicators in re-setting thelatter when released.

Upon the forward sides of the rods B are formed or secured beveledprojections or shoulders G which co-operate with a supporting bar totemporarily sustain the rods B in elevated position, with theirindicators exposed, as will be hereinafter described.

The key-levers H are strung upon a horizontal shaft I near the front ofthe machine as usual, and have spiral springs II connected to them inrear of their pivotal support, to aid in re-setting them. The respectivekey levers are arranged approximately in line with the respectiveindicator rods B which correspond to them, and interposed between therear end of each lever and its corresponding rod is a lever J, uponwhose rear end the rod rests. These levers J are strung upon ahorizontal shaft K. The front end of each lever is provided with a notchor mouth L and a beveled face M, which co-operate with a spring-plug Ncarried in a bore in the rear end of the corresponding key-lever. Theplugs N are normally pressed outward by springs N confined in the boresbehind them and may be forced inward against the pressure of thesprings. When the front end of any key-lever is depressed and its rearend thereby lifted the rear end of the plug N strikes the beveled face Mof the lever J and the plug is forced into its housing as its rear endrides up over said face. When the end of the plug passes above the faceM it will spring rearward again into the notch L of the lever J.

It will be seen that the lever J and the indicator rod resting upon itwill not havebeen moved by this operation, but when the keylever isreleased and its rear end begins to descend the end of the plug N willengage the lower wall of the notch L in the forward end of the lever J,and carry the forward end of the lever down with it and thereby lift theindicator rod resting upon therear end of the lever. \Vhen the rear endof the plug Nand forward end of the lever J in their downward movementreach the point where the arcs of the respective circles described bythem intersect each other the plug will become disengaged from andrelease the lever and the latter will be re-set by the spring 0, one ofwhich is connected at one end to each of the levers J in front of theshaft K and at its other end to a rod P extending across the entiremachine.

Supported at its ends by pendent arms Q fast upon a rock-shaft R is theindicator-sup porting bar S which co-operates with the shoulders G uponthe forward sides of the indicator-rods B. Projecting forwardly from therock-shaft B, one near each end, are two arms T, T, resting on the rodP, and whose front ends are connected by a rod U extending across theentire machine above the rear ends of the key-levers H. It results fromthis construction thatwhenever the rodUis lifted the shaft R will berocked and the supporting bar S thrown forward from under the shoulder Gof any indicator-rod that may be resting upon it, thereby releasing suchrod and permitting its indicator to drop out of sight.

When the front end of any key-lever is depressed to its limit of strokeits rear end will strike the rod U and throw forward the bar S torelease any indicators which may be supported upon it. When thekey-lever is released and its rear end begins to descend the rod U willdrop back again and the bar S resume its normal position, and when theshoulder G of the rod which is beinglifted by the rear end of the leverJ corresponding to the operated key-lever reaches the bar S it will pushit slightly forward, pass it, and catch upon it when the lever J isreleased and re-set.

From the foregoing description it will be seen that when the front endof any key lever is depressed to its full extent its rear end will liftthe rod U and move the supporting bar S to release any indicator rod orrods which may be upheld by it; and that when the keylever is releasedand re-set the indicator rod corresponding to it will be lifted by thelever J and caught upon and held up by the supporting bar S.

It will of course be understood that the mechanism of the machine is tobe inclosed in a suitable casing having a window at which the indicatorsare exposed to view when lifted by the operation of their appropriatekey-levers, as is usual in this class of machines.

My invention, in its broader scope, is not limited to the particularmethod and means I have shown and described for lifting the rods andindicators upon the return strokes of the keys, but contemplates broadlysuch new mode of operation, when accomplished by any means coming withinthe terms of my respective claims. Again, where levers such as thelevers J are employed between the key levers and indicator rods, anysuitable form of connecting devices between their front ends and therear ends of the key levers may be employed in plaeeof the spring-plugswhich I have shown. For instance, in Fig. 3 I have illustrated a gravitytrip V which may be substituted for the spring-plug. These trips arepivoted upon the sides of the keys, in line with the levers J, and theirrear ends or noses project to the rear of the ends of the keys intoposition to co-operate with the front ends of the levers J. \Vhen thefront end of a keylever is depressed and its rear end lifted the nose ofits trip V will ride up over the face M of the corresponding leverJ,being depressed as it passes,and when it gets above said face thegravity of the forward end of the trip will re-set it and throw the noseof the trip up ward and rearward overthe end of the lever. When thekey-lever is released and its rear end descends the rear end of its tripwill engage the end of the lever J, and as the trip cannotyield in thisdirection it will carrythe front end of the lever J down with it andlift its rear end and the indicator-rod resting thereon. W'hen therearend of the trip and the forward end of the lever J reach the point atwhich the arcs of the circles described by them intersect each otherthey will become disconnected and the spring 0 will reset the lever, asbefore explained. Furthermore, the particular method I have describedfor moving the supporting bar S upon the positive strokes of the keylevers, to release the elevated indicators, is not essential to myinveir tion in its broader scope, and other methods may be substitutedfor it.

Having thus fully described my invention, 1 claim- 1.
